Seismic Silence?

Recent studies reveal that the COVID-19 pandemic period has been the quietest period of human activity in the seismic record.

It makes you wonder about the cumulative background noise that human activity generates as a constant vibrational hum of socioeconomic activity across the crust and into the subsurface body of the Earth. In what ways does this recursively bootstrap into longer-term seismic system activity as a matter of harmonic resonance? It may be relatively negligible, but is still a component in a complex adaptive network of interdependent components and systems.

It is surely not possible (or plausible) to understand the total form, function and flow of energy (i.e. information) patterns cascading across (and as) the structure of this planet in high resolution without taking into account the oscillating buzz and hum of contemporary human activity. Where a missing electron in an atomic lattice might possess some of the properties of an actual particle (as a “quasiparticle”), we might consider that the absence of a thing also possesses mathematical or otherwise analytical and predictive properties and consequences.

What, if any, are the overall seismic system harmonic consequences of just such an acoustic void, conspicuous by its absence? Introducing an absence acts as an inverse presence.
